Solution Overview

Problem

Existing television decoding units lack efficient mechanisms for identifying and managing user access to content based on rating levels, particularly in scenarios where multiple users are present, leading to potential unauthorized access to adult or violent content.

Innovation Solution

A wireless communication system between access modules and television decoding units, utilizing RFID or NFC standards, allows for detection of access modules based on proximity and rating levels, enabling dynamic filtering and consumption tracking, with features like priority functions and pin code authentication to manage user profiles and viewing policies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pin code entry system is used for user identification, then user access control is implemented, but the system requires manual intervention and cannot automatically detect when a user leaves

Engineering Contradiction:

Improveaccess control reliabilityVSAvoidautomatic user detection

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system uses wireless communication modules that automatically detect and identify users without requiring manual pin code entry. The television decoding unit autonomously monitors for the presence of access modules and applies appropriate filtering based on detected user profiles, eliminating the need for manual intervention while maintaining reliable access control

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of entering pin codes is replaced with wireless electromagnetic communication between access modules and the television decoding unit. This substitution enables automatic detection and identification of users through wireless signals, removing the need for physical keyboard interaction while improving system responsiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple access modules are supported, then family-wide access management is enabled, but the device complexity increases

Engineering Contradiction:

Improvemulti-user supportVSAvoidaccess module management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The television decoding unit is designed with universal functionality to support multiple access modules simultaneously. Each module represents a different user profile with customized filtering preferences, allowing the system to serve multiple users with diverse requirements through a single integrated platform rather than requiring separate systems for each user

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system segments user access control into independent modular profiles, where each access module represents a discrete user identity with its own filtering preferences. This segmentation allows the complex multi-user management to be broken down into manageable individual profiles that can be independently configured and managed

Inventive Principle:

Principle #1Segmentation

3Reliability

If filtering is applied based on user profiles, then inappropriate content is blocked, but the system cannot quickly switch between different user contexts

Engineering Contradiction:

Improvecontent filtering effectivenessVSAvoidprofile switching speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

User profiles and filtering preferences are pre-configured and stored in the system before actual viewing occurs. When a user approaches or interacts with the television, the system instantly retrieves the pre-configured profile and applies the corresponding filtering rules, eliminating any delay in profile switching while maintaining effective content filtering

Inventive Principle:

Principle #10Preliminary action
